Ingredients for Blueberry Oatmeal Bars

Gather these simple ingredients before you start:

Dry Ingredients:

• 1 cup old-fashioned oats – Provides texture and fiber.
• 3/4 cup all-purpose flour (or gluten-free flour blend) – Helps bind the ingredients together.
• 1/3 cup light brown sugar – Adds a subtle caramel-like sweetness.
• 1/4 teaspoon baking soda – Gives a slight lift to the bars.
• 1/4 teaspoon salt – Enhances flavor.
• 1/2 teaspoon cinnamon (optional) – Adds warmth and depth.

Wet Ingredients:

• 6 tablespoons unsalted butter, melted (or coconut oil) – Helps hold the oat mixture together and adds richness.
• 1 teaspoon vanilla extract – Adds depth of flavor.

Blueberry Filling:

• 1 cup blueberries (fresh or frozen) – The star ingredient, bursting with natural sweetness.
• 1/4 cup granulated sugar – Helps balance the tartness of the blueberries.
• 2 teaspoons cornstarch – Thickens the filling for a jam-like consistency.

How to Make Blueberry Oatmeal Bars

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). Line an 8-inch square baking pan with parchment paper, leaving an overhang on the sides. This makes it easy to lift the bars out after baking.

Step 2: Make the Oat Mixture

In a large mixing bowl, combine the oats, flour, brown sugar, baking soda, salt, and cinnamon (if using). Stir until evenly mixed.

Add the melted butter and vanilla extract, and mix until the mixture becomes crumbly. This will be used for both the base and topping of the bars.

Step 3: Press the Base Layer

Press half of the oat mixture firmly into the bottom of the prepared baking pan. Use the back of a spoon or your hands to ensure an even, compact layer.

Step 4: Prepare the Blueberry Filling

In a separate bowl, toss the blueberries with the granulated sugar and cornstarch. This helps thicken the filling as it bakes and creates a jammy texture.

Spread the blueberry mixture evenly over the oat base.

Step 5: Add the Topping

Sprinkle the remaining oat mixture over the blueberries, pressing down gently to ensure everything sticks together.

Step 6: Bake

Place the pan in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and the blueberry filling is bubbly.

Step 7: Cool and Cut

Allow the bars to cool completely in the pan on a wire rack. This step is crucial, as it helps the bars set properly.

Once cooled, use the parchment paper overhang to lift the bars out of the pan. Cut into 12 squares and enjoy!

Tips for the Best Blueberry Oatmeal Bars

1. Use Fresh or Frozen Blueberries – If using frozen, do not thaw them before adding to the recipe to avoid excess moisture.
2. Let Them Cool Completely – Cutting too soon can make the bars crumble.
3. Enhance the Flavor – Add a pinch of nutmeg or lemon zest for a citrusy twist.
4. For a Crunchier Topping – Add chopped nuts, such as almonds or walnuts, to the oat mixture.
5. Drizzle with Glaze – A simple vanilla or almond glaze can add extra sweetness.

Variations & Substitutions

Want to switch things up? Try these fun variations:

• Mixed Berry Oatmeal Bars – Use a combination of raspberries, strawberries, and blackberries.
• Nutty Blueberry Oatmeal Bars – Stir in 1/4 cup chopped pecans or almonds for extra crunch.

• Gluten-Free Version – Swap all-purpose flour for a gluten-free flour blend.
